Raymond Smullyan starts his What Is the Name of His Book with a story of how he was fooled by his older brother:

(One) morning, my brother Emile (ten years my senior) came into my bedroom and said: "Well, Raymond, today is April's Fool Day, and I will foll you as you have never been fooled before!" I waited all day long for him to fool me, but he didn't. Late that night, my mother turned to Emile and said, "Emile, will you please fool the child!" Emile then turned to me, and the following dialogue ensued:
Emile: So, you expected me to fool you, didn't you?
Raymond: Yes.
Emile: But I didn't, did I?
Raymond: No.
Emile: But you expected me to, didn't you?
Raymond: Yes.
Emile: So I fooled you, didn't I?

A good example of a benefit drawn from older brothers and a nice introduction into the art of logic and logic argument.
